lMPROVEME-NT IN SlNGElNG-FURNACES.

Specification forming part of Letters Patent No. 170,018, dated November16, 1875; application filed August 30, 1875.

To all whom it may concern:

Be it known that I, BENJAMIN Rosa, of Cleveland, in the county ofGuyahoga and State of Ohio, have invented a certain new and ImprovedSingeing-Furnace; and I do hereby declare that the following is'a full,clear, and complete description thereof, reference being had to theaccompanying drawings, making part of the same.

Figure l'is a side elevation of the furnace. Fig. 2 is a plan view. Fig.3 is a front view. Fig. at is a vertical transverse section.

Like letters of reference refer to like parts in the several views.

This invention is for singeing the hair from hogs, by means of afurnace, through which the animals are conveyed by an apparatus.

The construction and operation of said furnace and apparatus aresubstantially as follows: 7

In the drawing, A represents the ground whereon is erected the furnace Breferred to. C, Fig. 3, is the fire-place; D, the grate; E, the ash-pit,and F, Fig. 4, the reverberatory Said chamber has an opening on eachside, as will be seen at a a, Fig. 4,-to which is fitted arevolving dooror its equivalent, consisting of the four radial plates 1), c, d, and cjournaled in the sides of the openings at the points f. From each sideof the furnace projects a pair of arms, G, in the outer ends of which isjournaled a shaft, H, Figs. 1 and 2. On said shaft is securedsprocket-whcelsI 1, arranged in relation to each other that the wheelson one are in direct line with those on the opposite side, as will beseen in Fig. 2. Directly under the fire place is a reservoir, J, Fig. 4,inwhich is arranged guide-wheels, K, correspondin g in number to thesprocket-wheels on one side of the furnace, and to which they arerespectively related. L is an endless chain passing over thesprocket-wheels down to and under the guide-wheels K, as shown in Fig.4, in which it will be seen that the chains pass through the furnacefrom wheel to wheel, the

tension of the chains being such as to keep them. horizontal... M is acog-wheel, whereby the sprocket-wheels and chains are operated by thepinion N, Fig. 2, on the shaft.

for that purpose.

The practical operation of the above-described furnace is as follows:The purpose of this invention is for singeing the hair from hogs,instead of removing the same by scalding. To this end the animal to betreated is laid upon the chains between the arms h. Now, on rotating thechains in direction of the arrows by means of the crank P and wheel andpinion M N, the animal will be carried forward to the revolving door,which it will push open, and continue to move onward into the furnace,(closing the door behind it,) wherein the hair is quickly singed fromthe body by the direct flame from below, and from that reverberated ordeflected from the crown of the chamber. The singed animal continues tomove onward across the furnace to the revolving d or on the oppositeside, which in like manner is pushed open, and thebody comes forth andis passed from the chains into a tub of hot water, wherein it is cleanedfor being dressed.

The chains in passing through the furnace become heated, which, however,are cooled off in passing through the reservoir J under the furnace,which is kept filled with cold water The fuel to be usedin the furnacebeing of any kind suitable for the purpose of burning quickly, the flamesoon scorches 0d the hair from the body; hence the body is simply runthrough the furnace, it not being retained therein long enough to heator scorch the flesh.

In'place of revolving doors there may be used doors arranged to slide upand down.

vertically by suitable means, or doors connected to the furnace byhinges or otherwise,

so as to open and close, as may be required in the operation of singeingtheanimal.

What I claim as my invention, and desire to secure by Letters Patent, is

The wheels I I, guide-wheels K, chains L, reservoir J, and furnace B,constructed and arranged to operate substantially in the mannor asdescribed, and for the purpose set forth.
